Patent FR-2670638-A1 (FR)
Title: Method and system for phase-shift optical transmission
Inventor: BERNARD BIOTTEAU
IPC: H04B10/60
Filed: 1990-12-17
Abstract: The frequency of a coherent optical transmission wave (16) is temporarily offset during modulation pulses so as to give rise to an alternate succession of phase shifts modifying this wave into a representation coded by a succession of bits to be transmitted. These modulation pulses are supplied by a coder (2) which controls the frequency of a laser emitter (14) injecting the transmission wave into an optical fibre (24). According to the invention, the characteristic duration (D) of these pulses lies between 15 and 35% of the duration (T) of the bits to be transmitted. Heterodyne reception means include a local oscillator (26), an optical mixer (30), a photodetector (34), and a demodulator (46). The invention applies to telecommunications.

Title: Method of construction, by means of the novel use of cellular concrete and a wooden frame (grid)
IPC: E04B2/56
Filed: 1993-06-25
Abstract: Method of rapidly erecting a construction for use as a dwelling, which is economic and of high performance. The method makes it possible to marry the properties of two materials (cellular concrete (2) and wood (1)) in order to obtain a "permanent" structure by prefabrication. It consists in producing a vertical framework of wood (1) (Class 4 treated), incorporating, "in advance", uprights in the thickness of the reinforced slabs of cellular concrete (2) and in tying the whole by means of a system of metal pins (3) and tie-bars and of wooden ties. The method enables constructions to be made which are adapted to the regions in which the wooden structures are traditionally to be seen.
